Utilization of Bioslurryfrom Biogas Plant as Fertilizer

Abstract

The conventional sources of energy are polluting the environment and getting depleted. The only option is renewable sources of energy like biogas. Disposal of large amount of bio gas slurry (BGS) producedis a major concern. Recycling of organic waste such as cattle dung, vegetable waste, food waste by the process of anaerobic digestion in the biogas plant (BGP) will be a great potential than producing any other fossil fuels. In many of the developing countries like India, cattle dung, crops residues will be produced in very large amount and hence it possible for producing bio gas and the bio slurry as the by-product. Hence, utilization of bio slurry as a fertilizer is an effective way. It increases the productivity of the soil. It is cheap and easily available fertilizer for the small scale farmers who could not afford in buying synthetic fertilizers. Bio slurry is nowadays being used as an effective source of fertilizer. It has high nitrogen (N), phosphorous (P) and potassium (K) that are considered to be the macro nutrients required for the flourishing growth of plants. It also contains some micro nutrients. It reduces the cost of natural organic fertilizer and increases the fertility of the soil.
